Q1. Arrange the following in the correct sequence representing the flow of genetic information in the central dogma of molecular biology:
आणविक जीवविज्ञान के केंद्रीय सिद्धांत (सेंट्रल डॉग्मा) में आनुवंशिक सूचना के प्रवाह को निरूपित करने वाले सही अनुक्रम में निम्नलिखित को व्यवस्थित कीजिए:
- A. DNA → RNA → Protein / DNA → RNA → प्रोटीन
- B. DNA → Protein → RNA / DNA → प्रोटीन → RNA
- C. Protein → RNA → DNA / प्रोटीन → RNA → DNA
- D. RNA → DNA → Protein / RNA → DNA → प्रोटीन
Solution
The central dogma states that information flows from DNA to RNA by transcription and from RNA to protein by translation, i.e. DNA → RNA → Protein.
केंद्रीय सिद्धांत के अनुसार सूचना DNA से RNA की ओर ट्रांसक्रिप्शन द्वारा तथा RNA से प्रोटीन की ओर ट्रांसलेशन द्वारा प्रवाहित होती है, अर्थात् DNA → RNA → प्रोटीन।
Q2. The number of standard α-amino acids from which the proteins of living organisms are commonly built is:
जीवित जीवों की प्रोटीनें सामान्यतः जितने मानक α-ऐमीनो अम्लों से बनी होती हैं, उनकी संख्या है:
- A. 20
- B. 16
- C. 10
- D. 24
Solution
Proteins are synthesised from a common set of 20 standard α-amino acids, of which some are essential and must be obtained from the diet.
प्रोटीनों का संश्लेषण 20 मानक α-ऐमीनो अम्लों के एक सामान्य समुच्चय से होता है, जिनमें से कुछ आवश्यक हैं और आहार से प्राप्त करने पड़ते हैं।
Q3. The double-helix model of DNA was proposed by Watson and Crick in the year:
DNA का द्विकुंडलिनी (डबल हेलिक्स) मॉडल वॉटसन और क्रिक द्वारा किस वर्ष में प्रस्तावित किया गया था?
- A. 1869
- B. 1961
- C. 1944
- D. 1953
Solution
James Watson and Francis Crick proposed the double-helix structure of DNA in 1953.
जेम्स वॉटसन और फ्रांसिस क्रिक ने 1953 में DNA की द्विकुंडलिनी संरचना प्रस्तावित की थी।
